Description

Дл  переработки платинитовой проволоки в ферроникель необходимо сн ть поверхностный борнокислый слой в щавелевой или лимонной кислоте с послед.у10щи- растворением медной оболочки в аммиачном растворе хлорной меди. Однако такой способ не  вл етс  экономичным.To process platinite wire into ferronickel, it is necessary to remove the surface boric acid layer in oxalic or citric acid with a subsequent dissolution of the copper sheath in an ammoniacal solution of chlorine copper. However, this method is not economical.

Эта операци  может быть заменена катодным восстановлением буры и анодным травлением меди, проводимых непрерывно в одной установке, состо щей из двух ванн дл  катодного восстановлени  буры в электролите из едкого натра и дл  анодного травлени  меди в электролите из серной кислоты .This operation can be replaced by cathode reduction of borax and anodic etching of copper, carried out continuously in one unit, consisting of two baths for cathodic reduction of borax in an electrolyte from caustic soda and for anodic etching of copper in an electrolyte from sulfuric acid.

Подвод тока к проволоке осуществл етс  известным бипол рным способом без непосредственного контакта с проволокой и состоит в том, что положительный полюс от источника тока электрически подключают к корпусу ванны с раствором щелочи, а отрицательный полюс -к корпусу ванны с раствором серной кпслоты.The current is supplied to the wire by a known bipolar method without direct contact with the wire and consists in that the positive pole from the current source is electrically connected to the body of the bath with an alkali solution, and the negative pole to the body of the bath with a sulfuric acid solution.

Проволока последовательно проходит через первую и вторую ванны будучн в первой ванне катодом , а во второй-анодом.The wire passes sequentially through the first and second baths in the first bath by the cathode, and in the second by the anode.

За катодный период снпмаетс  борнокислый слоГ платпнита в первой ванне, а во BTOpoii ванне происходит анодное травление медп при режиме, гарантирующем полную пассивность ферроникел .During the cathode period, the fenic acid layer of platpnite is removed in the first bath, and in the BTOpoii bath, anodic etching of medp occurs under the regime that guarantees the complete passivity of the ferronickel.

Предмет изобретен и  The subject is invented and

Способ переработки некондиционпого платинита на электролитической установке непрерывного и многократного действи , отлпч а ю щ п и с   тем, что борнокислый слой платинита катодной обработкой в одной секции установки, а во второй секции , с целью предотвращепи  растворени  ферроникел , анодное травление меди ведут при режиме, гарантирующем полную пассивность ферроникел .The method of processing non-conforming platinite on an electrolytic installation of continuous and repeated action, is perfect in that the boric acid layer of platinite is cathodic treated in one section of the installation, and in the second section, in order to prevent dissolution of ferronickel, anodic etching of copper is carried out under the mode guaranteeing complete passivity of ferronickel.
